What is the purpose of a negative pressure enclosure during removal?

A negative pressure enclosure plays a critical role in asbestos removal operations by creating a controlled environment that prevents the escape of dangerous asbestos fibers into the surrounding area. This is achieved by maintaining lower air pressure inside the enclosure compared to outside, effectively containing any airborne asbestos particles that may be generated during the removal process. This safety measure is essential to protect both workers and the general public by minimizing the risk of asbestos exposure, which can have serious health implications.

In contrast to other potential purposes of enclosures, a negative pressure setup does not primarily enhance visibility for workers, reduce noise levels, or ensure quick material removal. These aspects may be relevant in some contexts but do not pertain to the fundamental function of a negative pressure enclosure during asbestos abatement. The main focus remains on environmental safety and containment, which is why the correct answer emphasizes the prevention of asbestos fiber escape.
